Aikido all in one 5687 tube pre / louder in right Channel

Are you talking about measuring between pin 8 and 4 and pin 8 and 5? Pin 8 being the heater CT?

OR

At the xformer? yes, 12VCT would be 6VAC from each "hot" to the CT since you are wiring the secondaries in series and you would be rectifying 12VAC to DC.

At the transformer

did you measure the heater voltage at each tube and yank them one by one to see if one tube is drawing a bunch of current? Do you get 12V across pins 4 and 5 of each tube with the tubes in? Tubes out?

Also, make sure you have the correct secondaries wired in series.

yeah, I check the tubes... when measured across pin 4 and 5 I only get 7.5vdc with tubes in.
yes. I checked the secondaries, that was the first thing I checked.

i also checked the setting resister for the voltage regulator

Got home from work today and went strait to work on my aikido? I disconnect the center tap and reconfigure the filament supply to a full wave bridge and measured to see what I have, 12vdc!...Yay! The instructions on the manual was a litle confusing to me but I am glad I have it straighten out.

Thanks everyone for helping!

awesome... Glad you got it sorted out.

Sometimes Broskie must be enjoying a few ipa's when he writes the manuals. The octal all in one has too many errors and discrepancies to count.

I never built any kit before, reading instructions were never my best attribute. The aikido can be configured so many different way that it can be confusing, I'm just glad that I learn something along the way and didn't have any major disaster.
